Abstract: 517,542. Equipoising-mechanism for lamp &c. supports; brackets. TRYTHALL, W. C. July'28, 1938, No. 22468. [Classes 52 (iii) and 52 (v)] A self-balanced support for an electric lamp or other electric appliance comprises arm members and elbow joints which are in appearance perfectly symmetrical throughout, and constitute housings .for the electric conductors and for spiral springs situated within the elbow joints, so that the conductors cannot be detected at any point of the jointed arms. As applied to a desk stand.for an electric lamp, Figs. 1, 2, a heavy base 1 supports a disc member 2 by means of a ball-bearing pivot 3. On opposite sides of the disc member 2 are secured by a screw 15 a pair of tubular arms 6 connected to the disc member 2 by means of a pin 21 and spiral springs 10, 10<1>. A similar joint is employed at the upper end of the arms 6 to carry a tubular arm 22 on which the electric lamp is mounted by a universal joint. The spiral springs tend to counteract the weight of the lamp, and the screws 15 may be used to regulate the frictional resistance of the joints. The position of the pin 21 in the pivot 3 may be changed in order to vary the. rest position of the arms. The electric cable 26 is led to the lamp through a circular plate 5 bearing a switch 24 and rotatable with the pivot 3. In a modification, Fig. 5, one spring only is used at each joint and one end of the spring is selectively attached to the member 2 or 9 by hooking the end into one of a number of slots in a circular flange 27 projecting from the members. The friction-adjusting screws 15 press the flanges 27 against steel washers 28. A spring washer 28<1> is interposed between the members 8<1>, 9 and 7<1>, 2.

Title: Improvements in or relating to generators of high frequency electrical signals of rectangular waveform
Inventor: LAND LEONARD ERNEST
IPC: H03K3/04
Filed: 1949-09-02
Abstract: 666,813. Valve circuits. GENERAL ELECTRIC CO., Ltd. Aug. 28, 1950 [Sept. 2, 1949], No. 22806/49. Class 40 (vi). A rectangular waveform generator comprises a pentode type valve having its anode and control grid connected via resistors to H.T.+ and its cathode connected to H.T. -, a diode is connected with its anode to the control grid of the pentode valve and first and second signals of the same waveform are applied to the cathode and anode of the diode respectively, the second signal being such that it neutralizes any part of the first signal which appears at the diode anode due to its inter-electrode capacity, and in this way the generator operates effectively at a high pulse repetition frequency. The Figure shows a generator in which a sinusoidal voltage having a frequency equal to the required P.R.F. is applied from an input 15 to a circuit 8, 9 which is resonant at the same frequency. Any part of the signal passed to the anode of diode 7 via the cathode/anode inter-electrode capacity is neutralized by capacitor 10. The pentode 1 is normally conducting due to its slightly positive control grid potential but during the negative portions of the sinusoidal voltage at the cathode of diode 7 the diode conducts, the control grid of pentode 1 drops rapidly to cut-off its anode potential then rising until after the sinusoidal voltage has passed through its minimum value and is rising, diode 7 is rendered non-conducting again, pentode 1 conducts and its anode voltage falls, the cycle then being repeated. Tapping 11 on inductor 8 is preferably connected to the mid-point of the inductor, thereby giving the minimum effective input capacity at the control grid of pentode 1. The " mark-space ratio " of the rectangular wave may be altered by varying the voltage of the cathode of diode 7 relative to that of the cathode of the pentode 1. The circuit may be used as a pulse shortening circuit by applying a pulse to the input 15 so that the resonant circuit 8, 9 " rings " but is so damped that only the first cycle of the damped waveform operates the generator. The rectangular waveform output may be integrated to produce a saw-tooth waveform.

Abstract: 324,937. Fairweather, H. G. C., (National Acme Co.). Aug. 7, 1928. Interconnecting guard or protector with starting-gear. - In '' Gridley " multiplespindle and other automatic screw machines having a shaft adapted to be driven alternatively by a power clutch or by hand, means interconnected with the clutchshifting gear are provided to prevent attachment of a band-crank to the shaft while the clutch is engaged, and to prevent clutch engagement while the crank is in place, in order to avoid injury to the operator. In a " Gridley " machine, the transverse shaft 2 is driven at high speed through a clutch 3 and receives at its end 9 a detachable hand-crank 10 for turning the machine during tooling, repairs, &c. The safety device, which is applicable to existing machines, comprises a rock-shaft 16, borne by brackets 12, 13 and carrying a manipulating- lever 17 with a recess 18 to fit over the shaft end 9, and an arm 19 provided with a pin 20 engaging a notched block 28 slidable in a swinging arm 24. The arm 24, which carries an extension 25 connected to the hand control-bar 8 for the clutch 3, is secured to a shaft 26, which is oscillated by the automatic clutch-control cam 6 acting on an arm 5, and carries loosely the clutchfork 4. The shaft 7 of the cam 6 is geared to the shaft 2, but receives also a slow-speed drive from a different source. When the lever 17 is thrown over to mask the shaft end, as shown in Fig. 5, the block 28 projects a pin 27 into a hole in the fork 4, which is thus coupled up to shift the power clutch into engagement, manually or automatically, the pin 20 engaging an orifice 23 in the arm 24, so locking the lever 17. If, when the lever 17 is withdrawn and the handle 10 is in place, the arm 24 is idly rocked forward, the pin 20 engages a second orifice 22 to lock the lever 17. A spring detent 29 coacts with sloped faces on a fixed part 30 to bias the lever 17 to its extreme positions.
